In this tutorial, we talk about plot variables such as Euler angle, effective stress, and fiber stretch.
We add new fiber stretch variables in a material mixture definition using two different methods: one in FEBioStudio and the other in a text editor.
We also briefly discuss navigating and editing .feb files in FEBioStudio and editing the .xml file in a text editor directly, as well as the FEBio Forum, a very valuable tool.
